On a related note, I feel like this issue (non-retina, retina, iphone 5 version, ipad version, older iOS support, etc) and the over-saturated app store have really stifled the indie development world. It takes a lot more effort to make a nicely packaged app today than in 2008-2009, and then you launch on the store and you're just one in 800,000 or w/e.

To me, it's kind of like how the first people on Youtube now have millions of views, but good luck starting a new YT account today...
